Shipping Notice
EGBATT has set a high standard for shipping lithium batteries. As lithium ion batteries fall under DG (dangerous goods) category, they use high-quality DG boxes or DG wooden cases to pack the batteries along with thick foam. This ensures that the batteries are delivered to customers in the best possible condition and without any damage.

- By express or Air shipping like UPS, DHL, Fedex.
- Shipping by sea to port or to door service.
- FAC to Customer's forwarder company in China.
EGBATT ensures that all of its batteries meet the MSDS and UN38.3 standards. The packaging requirements for lithium batteries shipped by sea depend on the Watt-hour rating for lithium ion cells or batteries, or the lithium metal content for lithium metal cells or batteries. The packaging needs to meet UN specifications or be strong and rigid packing that can withstand the shocks, mechanical handling, and loading encountered during transport.
Shipping Regulation
If you are an international customer, please note that products will be shipped directly from China. To place your order, please contact odmbattery@outlook.com manually, rather than ordering on the website, as shipping costs may be inaccurate for regions outside of the USA.
